PERRY J. GARRISON, 0F OXFORD, MICHIGAN MEANS FOR COOLING INTERNAL-COMBUSTION ENGINES.

provementfin Means for Cooling Internal- Combustion Engines, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the of this specification.

My invention relates to means for cooling internal combustion engines and for supplying the carbureter with moistened air free from dust or dirt, that'itsefliciency may be increased.

One object of the present invention is to dispense with the usual radiator employing a plurality of thin metal tubes through which water from the water jacket of the engine sists in a water -chamber,0ccupyin to assist the coolin circulates that the water may be cooled before returning it again to the engine,--and also to dispense with the usual fan employed to insure the passage of air around the tubes action. a One feature of t e present invention 001111- t e same relative position as the usual ra lator, said chamber containing a pipe openingat one end into the water pipe connection between the water chamber and the Water jacket of the engine; the other open end of the pipe extending throu h the wall 'of the chamber that air from t e outside may be drawn through the pipe by the circulation of water through the water jacket -that it ma also assist in the cooling of the engine. X further object is. to supply moistened air to the carburetor by providing a connecwater jacket of the engine,'the air in turn bein urified in its passage.

Wilt the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement. of parts and in the details of construction hereinafter described and claimed, it being underst od that Specification of Letters Patent.

changes may be made in the precise embodiment of the invention within the scope of what is claimed without departing from the spirit of the same. i l

In the aocompan i drawings Figure 1 is e ,si e e evation ofan internal combustion engine showing the water chamher and connections between it and the water acket of the'engine and also with the can bureter.

Fig. 2 is a rear elevation of the water chamber with partsbroken away and in section to more clearly disclose its construction.

, Fig. '3 is a side elevation of the engine and water chamber w th parts in section, showing the connection-between the water chamher and the water jacket of the engine as XITFIBWGF from the. side opposite that shown in ig. '4 is a vertical cross-sectional View through the water chamber on or about line 4-4 of Fig. 2.

Fig. 5 is a horizontal cross-sectional View of the water chamber on or about line 5 5- of F if. 2.

'Re erring now to the letters of reference placed upon the drawings A, denotes an internal combustion engine. B, its water jacket. G, its intake manifold. D, its exhaust manifold. E, a carbureter connected'with the intake and exhaust manifolds and F, an exhaust G, designates the water chamber, preferably constructed of cast metal, divided adj acent to its lower end,-the lower portion being secured to the upper part by bolts g, extending through flanges formed on the upper and lower sections.

H, indicates a water pie connection between the water jacket an the water chamber for returning the water to the latter and I, indicates a water pipe connection leading from the water'chamber to the water jacket.

J, denotes a U-sliaped pipe lodged within the water chamber, its: upper open ends projecting through the wall of the radiator to K, indicates a 'pipe connection between the U-shaped pipe and pipe leading to a I opening within the water. pipe connection I,

leading from the water chamber back to the "engine; L, is a filler cap, blyl removing which the chamber Gr, may be led with water. M, is a pi e connection between the water chamber a ove the water level therein and the usual air inlet to the carbureter. N, is a fuel pipe leading to the carbureter under control of a suitable valve N. The carbureter shown forms no part of the present invention but is the subject matter of another application and it will therefore require no detailed description here, as any suitable carbureter may be employed in connection with the water chamber.

Upon the engine operating under lts own power, its suction stroke will draw air from of the engine, the other .be found sufiicient for all purposes.

What I claim is 1. The combination with an internal combustion engine, of a water chamber, suitable pipe connections between the water chamber and the water' jacket of the engine to provide 'for a circulation of water therethrough, and a pipe having an open end sleeved within the water return connection between the water tank and the water jacket end of the pipe being open to the outer air to admit the air therethrough into said water pipe connection and thence to the water jacket of the engine.

2. The combination with an internal com- .bustion engine and a' 'carbureter connected with its intake manifold, of a chamber,

- suitable pipe connections between the chamber and the water jacket of the-engine, a pipe connecting the chamber with the air intake to the carbureter, and a pipe having an open end sleeved within the return connection between the chamber and the water jacket of the engine, the other end of the pipe being open to atmosphere, whereby air may be drawn through the pipe from the outer atmosphere through the water jacket of the engine, to cool the water in said jacket.

3. The combination with an internal combustion engine and a carbureter connected with its intake manifold, of a water chamber, suitable pipe connections between the water chamber and the water jacket of the engine, a pipe connecting the water chamber above the water level in the latter with the air intake to the carbureter, a U-shaped pipe within the water chamber with its open ends projecting through the wall of the water chamber to admit air into said pipe, and an open ended pipe leading from said U-shaped pipe into the return water pipe connection between the water chamber and the water jacket of the engine, whereby the outer atmosphere may be drawn through the water jacket of the engine to cool the water circuating through the latter.

4. The combination with an internal combustion engine and a carbureter connected with its intake manifold, of a cast metal water chamber divided to admit of assembling suitable pipe fittings therein, a water pipe connection between the water jacket of the engine and the water chamber for the circulatlon of water therethrough, a pipe connecting the water chamber above its water level with the air intake to the carbureter, a pipe fitting lodged within the water chamber extending through the wall of the chamber and open for the admission of air to said fitting and an open pipe connection extending from said fitting to and projecting within the said water pipe returnbetween the water chamber and the water jacket of the engine, whereby the outer air may be drawn through the water jacket of the engine.

In testimony whereof, I sign this specification in the presence of two witnesses.
